; Stubs for the audio routines in rom bank 10
; They use JSRFAR to select the correct bank, so user code doesn't have to bother.
;
; The stubs here still use the romsub definitions of the routines from syslib, but those are
; just the jump addresses and are unaware of the kernal bank. Wrapping in JSRFAR fixes this.
